A locking mechanism for securing a center beam of a bed frame to the cross bars that enable the assembler to complete the assembly of the bed frame completely without the need for hand tools or securing implements to aid in the assembly. With a queen size bed frame or smaller, the cross bar members are joined together in overlapping manner to form cross bars and the center beam is secured to the cross bars by use of the present locking mechanism. In the case of a king size or a California king size bed frame, a universal extension bar is provided that can be used to join the cross bar members of either size bed frame and a extension cap is also provided that is affixed to the universal extension bar having indicia that instructs the assembler in the proper assembly of the particular bed frame.
